EKG certification Certification EKG Stress Testing & Holter Monitoring 3

Question 1

What minimum duration is standard for a conventional Holter monitor recording to capture intermittent arrhythmias?

Accepted Answer

24 hours

Answer

The standard Holter monitoring duration is 24 hours, which captures a full cycle of daily activities including sleep to detect intermittent arrhythmias.

Question 2

Which EKG lead placement configuration is most commonly used in a standard Holter monitor setup?

Accepted Answer

Modified 5-lead or 7-lead chest configuration

Answer

Holter monitors typically use a modified 5-lead or 7-lead configuration attached to the chest to approximate standard EKG views while allowing patient mobility.

Question 3

During a Bruce Protocol stress test, what happens at each successive stage?

Accepted Answer

Both treadmill speed and incline increase

Answer

The Bruce Protocol increases both speed and grade at each 3-minute stage to progressively intensify the cardiac workload.

Question 4

A patient's stress test EKG shows 2 mm horizontal ST depression in leads V4-V6 at peak exercise. What does this finding most likely indicate?

Accepted Answer

Significant myocardial ischemia in the lateral wall

Answer

Horizontal ST depression of 2 mm or more during exercise strongly suggests significant myocardial ischemia in the territory supplied by the affected coronary artery.

Question 5

What is the primary advantage of an event monitor over a standard 24-hour Holter monitor?

Accepted Answer

It can record over weeks to capture infrequent symptoms

Answer

Event monitors can be worn for weeks or months, making them ideal for capturing arrhythmias that occur too infrequently to be caught in a 24-hour Holter recording.
